Emitter clogging has been an important factor restricting the application of drip irrigation system. In order toimprove the anti-clogging ability of the dripper, the front part of the drip irrigation system needs to be equipped withmulti-stage filtration equipment or facilities. This study investigated the effect of different fertilizers on the sediment transportcapacity during the integrated irrigation of muddy water with fertilizer in order to make rational allocation of filtrationequipment and facilities of the first drip irrigation system, to reduce the cost of filtration facilities and to improve the efficiencyof drip irrigation system. A total of 3 kinds of fertilizers (urea, potassium sulfate and water-soluble compound fertilizer) aswell as 3 different concentrations (1%, 2% and 3%) were chosen to carry out intermittent irrigation clogging test in muddywater with the sediment concentration of 1 g/L. The accumulated sediment, discharge sediment of drippers and rate ofdischarge sediment for drippers were analyzed. Tap water was applied as the test water. Experimental sediment was taken fromriver flood beach silts along Weihe River in Shaanxi Yangling. The working pressure of this test was set to 70 kPa based onthe preliminary experiment results. In order to increase irrigation times of this experiment, the test stopped when the averagerelative flow rate was below 70%. The test also stopped after 20 times of irrigation even though the relative flow rate was stillabove 70%. The results showed that the application of muddy water could enhance the sediment transport capacity of dripper.Different types and concentrations of fertilizer had different effects on the sediment transport capacity of dripper. Sedimenttransport capacity of dripper increased with rising urea concentrations. Compared with no fertilization treatment, when the ureaconcentration was 3%, the capacity value increased by 11% (P<0.05). Sediment transport capacity of dripper decreased withthe rising concentrations of potassium sulfate and compound fertilizer. As the concentration of potassium sulfate was 1%, thesediment transport capacity of dripper was significantly higher than that without fertilization(P<0.05) but as the concentrationof compound fertilizer was above 2%, sediment transport capacity of dripper was lower than no fertilizer treatment. The slopeof the fitted straight line between the standardized accumulated sediment and the standardized accumulated irrigation amountcould be used as the evaluation index for sediment transport capacity of dripper. The smaller the slope indicated that as theirrigation volume increased, the output of sediment of the dripper was lower, and the sediment transport capacity of dripperwas also lower. The dripper was more likely to be clogged. Discharge sediment for drippers increased with the increasingfrequency of irrigation. At the later stage of irrigation, its growth slowed down. Fertilization increased the maximum value ofdischarge sediment for drippers. With the increase of irrigation times, the rate of discharge sediment for drippers graduallydecreased. After applying urea, rate of discharge sediment for drippers decreased with increasing irrigation times. Afterapplying urea in the muddy water, the viscosity coefficient of irrigation water decreased with the increase of fertilizerconcentration, while it increased with the rising concentration of compound fertilizer. After applying potassium sulfate inmuddy water, the coefficient of irrigation water viscosity was higher than that without fertilization. The fertilizer concentrationwas an important factor that affected drip sediment output capacity. Appropriate fertilization concentration should bedetermined according to different types of fertilizers. The results provide valuable information for determining theanti-clogging strategy of dripper and improving the sediment transport capacity of dripper to guide integrated drip irrigation ofwater and fertilizer with high sediment concentration in the Yellow River irrigated area.
